Dragon's Maze will feature all ten guilds from Ravnica. In the prerelease sealed format, players choose their guild and receive a guild pack of the appropriate guild, but it can also support a second guild. Each player attending the prerelease receives the same promotional card, which can not be played in the sealed deck (as opposed to the prerelases to Return to Ravnica and Gatecrash). The draft format for Dragon's Maze also reverts to the normal format of drafting the three sets in a block in reverse order of their release, in this case Dragon's Maze - Gatecrash - Return to Ravnica.

Booster packs for Dragon's Maze do not contain basic lands. Instead each booster contains either a Guild Gate, a Shock land, or a mythic rare land from Dragon's Maze in the appropriate ratio of their rarities. The Shock lands have the appropriate expansion symbols of Return to Ravnica and Gatecrash, but the Gates are part of Dragon's Maze and have a Dragon's Maze expansion symbol making them part of the set and thus marking the first time cards other than basic lands are printed multiple times within the same block.
